Siva Nagulu, the talented folk singer, got a rare opportunity to croon for 'Aa gattununtaava' song in Mega Power Star Ram Charan's Rangasthalam. This amateur singer was praised to the core by Devi Sri Prasad on the dais of pre release event of the movie.
However, Siva Nagulu's voice was replaced by Devi Sri Prasad's voice in the film which shocked Siva Nagulu. Having attended a TV channel's interview Siva Nagulu expressed his grief and said a singer was dead with the act of the film's musician.
Perhaps, the makers might have felt the singer's voice would not suit to Ram Charan. But then, it must be remembered that it was the second song sung by Devi after 'Entha Sakkagunnave' and his voice might turn monotonous with two songs in the film. Devi may get his decision justified in any means. But then, his act appears to be a permanent blot to his professional career.
